As was demonstrated with the relationship between loading frequency and stiffness (Complex modulus), standing loads greatly reduces the asphalt modulus. SHRP currently recommends an adjustment of one grade for slow traffic and two grades for standing traffic. For airport loadings, based on the CGSB grades currently used, an increase of two grades is recommended as an interim measure, for airport pavements when the airport is utilized by large jet aircraft. When applying the SUPERPAVE specification a degree of conservatism in the selection of the minimum design temperature is recommended when new pavement construction is undertaken. A reliability of 98% is considered warranted because low temperature cracking can occur with a single occurrence of the low temperature. When overlaying cracked asphalt or PCC pavements, the cracking will generally be controlled more by the underlying pavement and conservatism in the selection of the low pavement temperature is not warranted. For overlays, the low temperature selection should include consideration of the overlay thickness as a major factor in reflective cracking. The low temperature reliability should then be selected on the basis of the binders potential in contributing to thermal cracking severity. This recommendation is made recognizing that the binder selection alone will not prevent reflective cracking but needs to provide some resistance to significant deterioration of reflected cracks.” 2.0 SUPERPAVE DESIGN TEMPERATURE SELECTION PROCESS ehT eht fo noitanimreted eht si edarg rednib GP evaprepuS a gnitceles rof locotorp evaprepuS tnemevap design temperatures for the proposed construction site.
